Abstract

"PROCESSAMENTO DE CORRENTES DE C4 OLEFINA PARA A PRODUçãO MáXIMA DE PROPILENO". A fim de maximizar a produção de propileno quando o suprimento externo de etileno é limitado, o C4 cortado de um processo de craqueamento de hidrocarboneto é primeiro submetido à autometátese antes de qualquer remoção de isobutileno e sem qualquer adição de etileno. Isto favorece as reações que produzem propileno e pentenos. O etileno e propileno produzido são em seguida removidos deixando uma corrente dos C4<39>s e componentes mais pesados. O C5 e os componentes mais pesados são em seguida removidos deixando uma mistura de 1-buteno, 2-buteno, isobutileno, e butanos iso- e normais. O isobutileno é em seguida removido preferivelmente por um desisobutilenizador de hidroisomerização de destilação catalítica. A corrente de C4 livre de isobutileno é em seguida misturada com o produto de etileno removido do produto de autometátese junto com qualquer etileno externo fresco necessário e submetido à metátese convencional produzindo propileno adicional.
